A RIGID BODY DATABASE ON NORMAL GAIT

平移运动方程中的非平衡： 本研究的目的是评估在错误的程度， 运动的平移方程的实现与 使用人体的十五段刚体模型来评估 步态 几何模型和运动数据处理技术， 能够产生可接受的低水平的非平衡， 实现平移运动方程。 然而， 这些技术必须就其性能差提出质疑 在步态的更冲动的阶段。 机械发电： 研究了人体行走过程中与肌肉有关的能量产生。 以前的数据处理技术提供了平面上的联合功率项 与基于解剖学的坐标系统相关联。 问题与这个 技术包括：1）节段功率的过度表现，以及2） 功率时间历程的积分不符合惯性基准 框架要求。 联合功率项不平衡的重要性是 目前正在评估中。

Nonequilibrium in the Translational Equations of Motion: The purpose of this study was to evaluate the extent of error in the implementation of the translational equations of motion associated with the use of a fifteen segment rigid body model of the human form to evaluate gait. Geometric models and kinematic data processing techniques are capable of producing acceptably low levels of nonequilibrium when implementing the translational equations of motion. However, efficacy of these techniques must be questioned in regards to their poor performance during the more impulsive phases of gait. Mechanical Power Generation: Muscle related power generation in human walking has been evaluated. Previous data processing techniques provided joint power terms in planes associated with anatomically based coordinate systems. Problems with this technique included: 1) the over-representation of segmental power, and 2) integration of power time histories did not conform to inertial reference frame requirements. The significance of joint power term imbalances is currently being evaluated.
